Xojo example projects (API1 & API2)
Cyclic Redundancy Check: CRC8, CRC16, CRC32
This example Xojo project shows how CRC Calculations can be implemented in pure Xojo Code. Because CRC classes are not available in the Xojo Framework, one has to either use a 3rd Party Plugin - or calculate the Algorithm(s) manually.
This example is based on this documentation: Understanding CRC.
That article is also included as a PDF.

Xojo is a rapid application development for Desktop, Web, Mobile & Raspberry Pi.
The Desktop application Xojo example project CRCCalculatorDesktop.xojo_project is using:
- Xojo 2018r4
- API 1
The Web application Xojo example project CRCCalculatorWeb.xojo_project is using:
- Xojo 2023r3
- API 2
- Copy/paste the required CRC Calculator Classes into your project
- Create an instance of the Class
- by using a predefined Algorithm:
CRC16Calculator.CreateByType(CRC16Type.MODBUS) - or create a custom Calculator:
New CRC16Calculator("CRC-16/GENIBUS", &h1021, &hffff, false, false, &hffff)
- by using a predefined Algorithm:
- Get the result:
myCRCCalculatorInstance.Result("1234567890")
This repository contains Documentation about how to package a Xojo built Web Application in a Docker Image. The Web application Xojo example project CRCCalculatorWeb.xojo_project includes a Post Build Script which automates the task of building the Docker Image of the web application.
